Title: remove superfluous explicit private GState allocation

This API is deprecated under OS X 10.10. It is my understanding that this call is unnecessary since the graphics context is not modified by this subclass (```setUpGState``` is not implemented by the subclass). Modifications for the graphics context should be made using ```NSGraphicsContext```.
